The European Commission with the active contribution of NTUA, SWOV, VIAS Institute and KFV has published at the European Road Safety Observatory, the Speed and Speeding Thematic Report which emphasizes that driving at excessive or inappropriate speed is a major threat to safety on the road. It is estimated that 10 to 15% of all crashes and 30% of all fatal crashes are the direct result of speeding or inappropriate speed. It is also emphasized that safety systems in cars, such as intelligent speed assistance or electronic stability control can prevent speeding or reduce the consequences of speeding, while education and communication, in combination with and supporting other measures, are particularly important. Moreover, city-wide 30km/h speed limits and their enforcement has been shown to be the most efficient measure for quick reduction of crash and injury risks.


The Editorial for the Special Issue Vehicle Safe Motion in Mixed-Vehicle-Technology Environment authored by Stergios Mavromatis, George Yannis and Yasser Hassan has been published in the World Electric Vehicle Journal. This Special Issue aims to advance knowledge on vehicle safe motion during this critical transition period by bringing together recent research on mixed traffic flow dynamics, safety assessment, and intelligent control strategies. Collectively, the papers in this Special Issue provide scientific insights and practical tools that support safer, more efficient, and more resilient vehicle motion in increasingly complex mixed-technology traffic environments. The findings suggest that connectivity-enabled strategies, predictive control, and cooperative decision-making can mitigate safety risks while promoting smoother traffic flow and reduced energy consumption, particularly in complex settings such as work zones, tunnels, and intersections. Moreover, AI-based perception and traffic monitoring emerge as key enablers for real-time traffic management and energy-aware electric mobility.

The European Union has recently published its Mid-Point Progress Report on the 2021-2030 road safety strategy with the active contribution of NTUA. The results summarised in this Report illustrate how much can be achieved when actors at all levels – from individuals to EU-level governing structures – contribute to the Safe System approach, within their areas of responsibility. But the slow-down in progress towards Vision Zero – against a background of increased traffic growth and new societal and technological trends – calls into question whether the current road safety ‘toolbox’ is fit for the future. The Report reveals significant opportunities in order to ensure the EU remains on track to meet its 2030 objectives, namely: technological advances in vehicle safety, growing awareness of the economic benefits of investments in safety, an increasing political focus on sustainable mobility and the coordinated, sustained, and properly resourced efforts across the EU and within Member States at all levels of government and society.

The European Commission with the active contribution of NTUA, SWOV and KFV has published at the European Road Safety Observatory, the Main Figures Facts and Figures Report which examines road fatalities on European roads. According to this Report, there has been a 12% decrease in road fatalities for the EU27 between 2019 and 2024, with far more males than females being killed in road crashes. Moreover, 48% of total road fatalities are vulnerable road users (pedestrians, cyclists, moped riders and motorcyclists) and over a half of road fatalities occur on rural roads (53%). On urban roads, the share of killed pedestrians is highest with 34%.

The European Road Transport Research Advisory Council (ERTRAC) has published a Position Paper titled “Road Transport Research in Horizon Europe Follow-up”. ERTRAC and the Associations supporting this Position Paper are convinced that dedicated funding for Road Transport Research is necessary to address the systemic road transport research needs critical to improve the efficiency, sustainability, safety and resilience of the whole European mobility system. Furthermore, it highlights the need for continued investment in vehicle technologies, infrastructure, traffic management, automation, and connectivity, as well as strong public–private cooperation, which are critical for delivering safer, cleaner, and more efficient road transport systems.


Marios Sekadakis has successfully defended his PhD dissertation titled: “Safety Assessment and Behaviour Modelling of Take-Over Dynamics in Automated Driving: From Human Response to Network-Level Simulation”, under the supervision of NTUA Prof. George Yannis. This PhD developed an integrated framework to explain how take-over response, driving performance and safety in automated driving at SAE Levels 2 and 3 are shaped by transition context, driver state, interface design and vehicle state dynamics. By combining systematic review and meta-analysis, simulator experimentation, data-driven modelling, behavioural profiling and network-level traffic simulation, the dissertation examined the full chain from individual re-engagement behaviour to vehicle motion and mixed-traffic safety effects. This work demonstrates that safety during take-over transitions cannot be explained by take-over duration alone. It demonstrates how Human-Machine Interface (HMI) design, automation level, behavioural variability and roadway context interact to shape both vehicle-level and network-level safety, identifying where and why safety margins collapse during transitions. The findings provide a consistent evidence base for safer take-over management and more robust evaluation of future automated driving systems.


Maria Oikonomou has successfully defended her PhD thesis titled “Multilevel crash risk assessment under autonomous vehicle integration: From partial to full autonomy through urban traffic simulation”, under the supervision of NTUA Prof. George Yannis. The thesis develops a validated, simulation-based framework for estimating crash risk during the transition from partial to full Autonomous Vehicle (AV) deployment. A systematic review establishes an evidence-based repository of AV behavioural parameters to support traffic microsimulation. The methodology integrates conflict-based Surrogate Safety Measures and a novel Time-To-Collision-based conflict-to-crash-risk conversion procedure, validated through k-means clustering against observed crash patterns. Applied to a high-fidelity simulation model of central Athens, the framework evaluates fifteen AV deployment scenarios across varying penetration levels. The multilevel assessment includes road-level modelling with XGBoost and SHAP to quantify the influence of traffic, infrastructure and automation, and conflict-level spatial analysis using the Getis-Ord Gi* statistic and a binomial GAM to detect high-risk hotspots. Results reveal that crash risk initially increases in mixed-traffic conditions before decreasing as automated behaviour becomes dominant and stabilises network interactions.


The European Commission has recently published findings from Trendline project on key road safety performance indicators (KPIs), revealing significant gaps in compliance with basic safety measures across EU Member States. This data paints a troubling picture of speeding compliance, particularly in urban environments. In many countries, compliance falls below 50% on city roads—precisely where pedestrians, cyclists, and other vulnerable road users are most at risk. Furthermore, while driver seat-belt use shows strong compliance, often exceeding 95% on motorways, rear-seat belt use tells a different story. Moreover, although the data shows high overall compliance with alcohol limits, at approximately 98, the seemingly small 2% non-compliance rate translates to roughly five million impaired drivers on EU roads. These indicators support road safety strategies and monitoring efforts at both national and European levels as the EU works toward its 2030 road safety targets.
